Well, it’s Christmas day, for most of us anyways, so we’d thought counting down the five coolest and / or geekiest trees would be fitting. First up, we have a Tesla coil Christmas tree that Santa Clause absolutely loves. Continue reading to see them all.

5. Mountain Dew Christmas Tree

Mountain Dew has never looked more Christmasy, thanks to this homemade Christmas tree. The creation you see above was made possible by dedicating hundreds of soda cans, a 2-liter bottle, glue gun, PVC piping, metal wires, LED lights, and countless labor hours.

4. Computer Christmas Tree Mod

Aside from the lights and decorations, a fully-functional computer is concealed within this Christmas tree. Featuring a VIA Epia 5000 motherboard, 512MB of memory, 40GB HDD, and a Panasonic Slimline Combo drive. The tree now spends its days in the CPC Labs where it’s used as simple Internet client and Network PC for transferring files to and from our server.

3. Laser Christmas Tree

Why get a normal Christmas tree, when you’ve got the equipment and brains to build a laser-powered version? To help entertain shoppers in these tough economic times, these Japanese engineers decided to use lasers, fog machines, spotlights, and lots of computers to put on a high-tech show.

2. Tesla Coil Christmas Tree

The most striking feature of this Christmas tree is that it was created with a giant Tesla Coil. These incredible shots were captured using “a long exposure and a rotating colored filter, but the tree shape is outlined by sparks from a rotating rod on top of the Tesla coil.” This gives the “Eye of Sauron” effect. Imagine then if that rotating rod is able to be raised from horizontal to vertical while still rotating. 

1. LEGO Christmas Tree

On display inside London’s St Pancras International Station, this gigantic, 33-foot tall, Christmas tree was made from 600,000 LEGO bricks. It has “a thousand baubles dangling from its 172 branches, and is now lit up by a classic garland of LED lights.” Among the decorations is a cube with a QR code for more information and there’s some related treasure hunt competition, though we didn’t bother to look into it. After two months of construction, it has been unveiled to the public in St Pancras International Station this week, and even the typically jaded Londoners are finding themselves wowed by its blocky intricacy.
